Background Traumatic brain injury influences regulation of cerebral blood flow in animal models and in human studies. We reviewed the use of transcranial Doppler ultrasound (US) to monitor ...
A new formulation for the Doppler signal generation process in pulsatile flow has been developed enabling easier identification and quantification of the mechanisms involved in spectral broadening and ...
Objective: We demonstrate the use of a magnetic-resonance (MR)-compatible ultrasound (US) imaging probe using spatially resolved Doppler for diagnostic quality cardiovascular MR imaging (MRI) as an ...
The hypoechoic areas seen in tendinopathy on gray-scale ultrasound (US) offer limited information which can be enhanced by the use of power Doppler (PD) to identify hyperaemic neovasculature.7 10 14 ...
Using ultra-sensitive Doppler ultrasound to measure testicular flow, Rocher and colleagues reported a decrease by 60% and 80% (P<0.05) in arterial blood flow during the Valsalva maneuver in patients ...
The Doppler transducer will be pressed against the skin and moved around over the area of the artery being looked at. When blood flow is detected, you will hear a "whoosh, whoosh" sound. The probe ...
MITCHELL, S.D. (SDNW) – The snow’s blowing sideways, the heavy stuff. It’s one of the few winter storms this year and it happens to fall on the first days of March, calving season. I arrive ...
INDIANAPOLIS — The Storm Prediction Center has placed parts of central Indiana under an isolated risk of strong to severe storms starting tonight and continuing through the end of the week. The ...

INDIANAPOLIS — NASA forecast models show a spike in activity due to an ongoing Geomagnetic Storm tonight. If you have clear skies and are in a more rural area away from city lights, you may be able to ...
